CASE A.

T 0 all whom it may concern:

Be it known that I, GEO. W. OASILEAR, of Washington, in the county ofWashington and District of Columbia, have invented certain new anduseful Improvements in the Method of Engraving Bank-Note Plates; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawing making a partof this application.

My invention relates to a novel method of producing plates for printingbank notes, checks, bonds, &c., where lettering is used; and has for itsobject the production of such plates more rapidly and at much less costthan has been heretofore done.

Prior to my invention theusual way of en graving names and titles uponplates for printing bank-notes, &c., has been to cut the same by handwith the customary tools of the workman, the bordering, vignettes, 850.,being produced by the transferpress. WVhere a large number of plates arerequired, having dilferent names and titles thereon, the saving of timeand money in their production becomes a matter of grave importance, theknowledge of which has led me to this my present invention.

In order that those skilled in the art may fully understand the same, Iwill describe the various steps taken in my improved method.

I first engrave upon a sheet or plate of steel of the proper size acomplete alphabet of any required style, plain, ornamented, or script,in lower or upper case, as may be selected. I then harden this plate andtransfer the alphabet to the face of a soft-steel roll by means of thewell-known transfer-press. This produces the alphabet in relief on theface or periphery of the roll.

Figure 1 illustrates the first step, showing the alphabet as firstengraved upon the plate; and Fig. 2, a series of words or titlesproduced from the roll, which is accomplished by rolling in one letterat the time, the roll being turned to present such letters as aresuccessively required to form the words. Fig. 3 and Fig. 3 illustratetheroll with the alphabet taken up upon its periphery.

After the final plate is thus en 5 aved I then lay upon it anetching-ground, s h. as is used by engravers, and with the rul g-machincrule a shade around the letters, hich, when properly treated with acid,con 1; cts the letters all together; or they may, afw r being laid downproperly, be treated in any ther known manner; or the independent lett sof the alphabet on the roll may be shad or ornamented, as seen in theword an urn on the drawing. l 1

It will thus be seen that the t st or initial plate of any number andvariety I ay have the lettering engraved by mechanic j means in a lessnumber of hours than it W0 1 d require in days by the. present knownsyste and that any number of plates having v ying titles, &c., may beprinted or engrave from a single roll. 1 I

I am aware that the transfer ress is old, and do not wish to lay anyclaim o the broad idea of transferring letters orch f aoters from aplate to a roll and back to a pla e; I am also aware that bank-noteplates h ebeen engraved by means of rolls having ovable letters or typeinserted in their peri heries, and that engraving-rollers with prds,signs, and characters produced in relie upon their peripheriessubstantially in thenanner described in my invention have bee employed;but neither of these in their resp 1 two methods of operation produceresul I similar to mine, and consequently such I not claim; but l 1 WhatI do claim as new, and e-sire to secure by Letters Patent, is- 1 1 Themethod herein described 0, 1 engraving titles and words upon bank-no cplates by means .of a roll having a partial r complete alphabet produedupon its peri ery, as described, and operated substantial] :in themanner herein setforth. l 1

In testimony whereof I have 1 ereunto set my hand and seal this 27th daya March, A. D. 1873.
